My wife and I just returned home after two weeks on Long Island, the first week at Whistling Duck. We even saw a Whistling duck! The cottage is set on a beautiful lot on the water, oriented with a view across the water of the Clarence Town marina. The water is maybe 25 yards from the cottage. We saw rays on several days. When we were there, there was no sandy beach where the path stops at the water, just steps down into very shallow, calm water (inches). The beach started 25-50 yards to the south and went on for a mile or more to the end of the bay.
The cottage is just right for two people, right sized and well equipped. We were very impressed with the first class construction and high state of maintenance. Some of the specific things we enjoyed: big refrigerator that could make lots of ice, small Weber gas grill that works well, firm king size bed, fast/reliable wifi, outdoor shower with hot/cold water, glide chairs on front porch for watching the passage of time on the water, ceiling fans, nice decorating, attractive landscaping. It’s just a comfortable place to be, and a good base for exploring the island.
